cimag(3) Library Functions Manual cimag(3)
cimag, cimagf, cimagl - get imaginary part of a complex number
Math library (libm, -lm)
#include <complex.h> double cimag(double complex z); float cimagf(float complex z); long double cimagl(long double complex z);
These functions return the imaginary part of the complex number z. One has: z = creal(z) + I * cimag(z)

GCC also supports __imag__. That is a GNU extension.
